A few errata have been brought to our attention concerning Volume 1: On p.31, "jealously" should be "jealousy". (Thanks, Dad) On p.111, it is claimed that the star Vega is "two light years away", whereas in fact it's twenty-five light years from Earth. (Thanks, Steve) On p.110, in the first paragraph of the section "Messages to (and from) outer space", there are two "has been"'s in a row. (Thanks, Peter – three proofreaders missed that one) On p.174, last line, "Equiangular spiral" should be "Equiangular spirals" On p.208, the third illustration doesn't actually illustrate what's described ("If I multiply the number by itself and then subtract 2, that, too, is a function:"). The illustration rather depicts the simpler function that only involves substracting 2. (Thanks to Jim Propp for noticing that) On p.244, the last illustration contains a small, stray black line segment that shouldn't be there. Jim Propp has also suggested that there might be a slight problem with the lower illustration on p.177 (that "the suggested tangencies are only approximate"), but I'm not entirely sure about this and will look into it.
